Definitions
- the present invention relates to boilers for power plants and more particularly those using solid fuels containing carbonaceous materials.
- this type of boilers uses air as an oxidizer. This technology is proven, but it must face new requirements to capture C0 2 in the fumes from the combustion of these carbonaceous materials before being released into the atmosphere. It is of course possible to selectively extract the C0 2 contained in the fumes, but given their low content (15% by volume), this post-capture proves to be penalizing in yield and extremely costly.
- To reduce the amount of CO 2 produced it is known from the patents US Pat. No. 6,202,574 and US Pat. No. 6,505,567, to carry out the combustion using oxygen no longer diluted in nitrogen as in air, but oxygen diluted in recycled C0 2 .
- the boiler then produces only a gaseous stream of C0 2 and water vapor which can be dried and liquefied to be transported for a later use of C0 2 or for underground sequestration.
- O2 / CO2 combustion the selective step of extracting the C0 2 contained in the fumes, with high energy consumption, is eliminated, but there appears a new energy penalty resulting from the electrical consumption linked to the production of oxygen.
- cryogenic which is the only one available to date to produce large quantities of oxygen. The consumption due to the production of oxygen is such that it risks making the oxy-combustion technology economically prohibitive.
- there are high temperature oxygen transport membranes allowing oxygen to be extracted from the air.
- the object of the present invention is to provide a boiler using oxygen as an oxidizer which has both a high efficiency, a high compactness and a relatively reasonable cost.
- the boiler according to the invention is in a circulating fluidized bed, it uses solid fuels and oxygen obtained by membranes for producing oxygen at high temperature, and it is characterized in that the membranes are arranged in the bed. These membranes are for example of the OTM (Oxygen Transport Membranes) type.
- the membranes operate at more than 700 ° C. (between 700 and 1000 ° C.), their positioning in the external bed is particularly suitable since the temperature of the solids circulating in the external bed is from 750 to 900 ° C. This is particularly remarkable because the operating temperature windows of the circulating fluidized bed coincide with the optimal temperature window for use of the membranes.
- the membranes are traversed by pressurized air. In order to facilitate the extraction of air from the membranes, the one is slightly under pressure. The air comes from a blower or a compressor which provides a pressure higher than that prevailing in the fluidized enclosure.
- the membranes are placed in the fluidized solids of the outer bed.
- the hot solids taken from the main loop of circulating solids provide the heat input to maintain the membranes at the optimal operating temperature and they ensure the evacuation of oxygen from the outer wall of the membranes.
- the solids also provide excellent thermal contact with a very strong material flow sweeping the external walls of the membranes at the right temperature, which improves the kinetics of oxygen transfer compared to an exchange on gas. alone. Since the heat exchange takes place with solids and not with gas, the surface area of the membranes required may be smaller, which is essential for the compactness and economy of the technology.
- the possible adjustment of the flow rate of the solids feeding the membranes allows the temperature of the chambers of the outer bed to be adjusted. According to another characteristic, the membranes are placed above the fluidized solids of the outer bed.
- the outer bed is used to heat the gas such as recycled CO 2 used for the fluidization of the bed and which then ensures the thermal back-up and the evacuation of the oxygen.
- the membranes are disposed on at least part of the periphery of the perimeter of the lower hearth. This arrangement makes it possible to have additional membrane surfaces.
- the membranes constitute an assembly resting on the hearth of the hearth. The floor being fluidized by recycled CO 2 , the placement of the membranes on the hearth of the hearth is possible since the rigidity of the hearth reduces the mechanical stresses on the tubes and therefore makes it possible to have great lengths.
- the membranes consist of very long tubes supported by intermediate plates.
- the intermediate tubular plates may or may not be cooled with inlet and outlet boxes.
- the membranes consist of short length tubes with intermediate boxes.
- the tubes can be arranged in series or in parallel.
- the membranes consist of concentric tubes, the inner tube of which serves as a support for the outer membrane tube.
- the inner tube is rigid enough to allow the mechanical strength of the membranes.
- the inner tube has openings so that the oxygen in the air can pass through the membrane tube placed thereon and that it is rigid enough to improve the mechanical strength of the membranes.
- a spacer is placed between the two tubes so as to hold the outer tube. It is traversed by the air either in the same direction as the current in the annular space in this case it has openings allowing communications of the air from the internal tubes towards the annular space, or against the current with a communication at the end of the tube in this case it has no openings along its length.
- the air flows against the current in the space between the two tubes. In this case the two tubes do not have openings along their length, but they communicate at their ends. The air therefore travels through the first inner tube from end to end, then it passes through the inter tube and re-traverses the inter tube in the opposite direction.
- a dense fluidized bed is placed along the internal walls of the hearth.
- the supply of said dense fluidized bed containing the membranes by descending solids collected along the walls of the hearth makes it possible to increase the performance of the boiler at partial load and to lower its minimum load, because there is no then no longer needs to resort only to solids withdrawn from the external circulation which varies greatly depending on the load of the boiler, in particular at low load, which is an economic advantage for the operator.
- Capture areas of the dense bed can directly accommodate the membrane tubes whose CO 2 O 2 exhaust is directly integrated into the hearth without connecting sheaths.
- the air passing through the membranes is conveyed to a recovery boiler.
- the enthalpy contained in this oxygen-depleted air is recovered by said recovery boiler, then the depleted air and cooled to low temperature (around 80 ° C) because it is not corrosive, it is discharged directly into the atmosphere through the chimney.
- the recovery boiler on depleted air is tightly combined with a recovery boiler for combustion fumes leaving the home. The combination of the two recovery boilers makes the installation more compact, but they are separated in a sealed manner so as to only release air into the atmosphere, while the CO 2 is transferred to it for sequestration. or storage.

- the fluidized bed boiler 1 comprises a hearth 2 and a cyclone or separator 3 which allows the separation of the solids contained in the flue gases, a solids recirculation loop 4, an extraction of the solids 5 to a dense fluidized bed 6, called the outer bed, containing a set of membranes 7.
- a duct 30 carries the combustion fumes leaving the cyclone 3 to a heat recovery boiler 8.
- the outer bed 6 receives the solids 67 through the duct extraction 5, which are then reinjected into the hearth 2 through the conduit 60.
- the fluidization of the bed 6 is ensured by recycled CO 2 arriving through the conduit 61 and then leaves via conduit 62 to be reintroduced into the hearth 2 by injectors 63 arranged at several levels.
- the outside air arrives via a blower or compressor 70 then is directed towards the bed 6 by the pipe 71, it then passes the membranes 7 to come out through the pipe 72 which directs the depleted air to a boiler of recovery 9 to then be released into the atmosphere.
- the air arrives through the pipe 71 after being pressurized by the blower 70, the pressure must be slightly higher than that prevailing in the enclosure of the bed 6 in order to promote the extraction of oxygen from the air.
- the depleted air is sent through a pipe 72 to the recovery boiler 9 where it is cooled, then it is released into the atmosphere.
- the solids are separated in the cyclone 3 then directed by the conduit 4 either to the bed 6 by 5, or by the direct return conduit 20 to the hearth 2.
- the solids arriving in the bed 6 are cooled and then reinjected into the part bottom of the hearth 2.
- the bed 6 is fluidized by gas such as recycled CO 2 arriving via the line 61, this fluidizing gas mixes with the oxygen produced by the membranes 7 and is then conveyed to the lower part of the hearth 2 by the pipes 62.
- a dense fluidized bed 6a is placed at the bottom of the hearth 2, it contains membranes 7a.
- the descending solids are then collected along the wall of the hearth 2 and fall into the bed 6a located on part or all of the periphery of the hearth 2.
- a fluidizing gas such as recycled CO 2 , flows through the bed 6a and mixes with the oxygen released by the membranes 7a and leaves directly in the hearth 2 without requiring connection sheaths.
- the membranes 7 are very long and arranged along the length of the bed 6 and supported by intermediate tubular plates 64 which can be cooled or not.
- the air enters through the inlet box 65 and exits through the outlet box 66.
- FIG. 4 and 5 correspond to a bed 6 where the membranes 7 consist of tubes of short length which are arranged between boxes input 65 and output 66 intermediaries arranged in series ( Figure 4) or in parallel (Figure 5).
- the variant shown in Figure 6 is a membrane T consisting of a support tube 73 surrounded by the membrane tube 74. The air circulates inside the supp ort tube 73 comprising openings 73a which allow the oxygen to l air to be extracted and pass through the membrane 74.
- Figure 12 shows a particular arrangement of the variant shown in Figure 6, where the two tubes 73 and 74 are spaced to allow air to pass. They are linked together by spacers 75.
- FIG. 13 illustrates an arrangement where the two concentric tubes 73 and 74 are only open at their ends 730, 731 and 740.
- the membranes 7 are arranged in the bed 6 above the solids 67, in this case the fluidizing gas (for example CO; ⁇ recycled) is heated by the solids 67 and allows the membranes 7 to function properly by bringing the fluidizing gas to the right temperature which makes it possible to extract oxygen from the air and ensures its evacuation.
